High-performance epoxy resin modifier designed to significantly improve impact resistance and fracture toughness without compromising thermal stability.
Low-viscosity liquid formulation ensures excellent compatibility and homogeneous dispersion in standard epoxy systems.
Enables room-temperature or elevated-temperature curing with minimal effect on gel time and pot life.
Halogen-free and REACH-compliant, supporting sustainable composite and adhesive manufacturing.
Enhances interlaminar shear strength (ILSS) in fiber-reinforced composites, particularly carbon and glass fiber laminates.
Aerospace structural adhesives and prepreg matrices for primary and secondary components.
Wind turbine blade resins requiring fatigue-resistant, crack-arresting performance.
High-end automotive under-hood composites exposed to thermal cycling and mechanical shock.
Electronics encapsulants and potting compounds demanding dielectric integrity and mechanical durability.
Railway interior panels and structural bonding systems meeting stringent fire-smoke-toxicity (FST) requirements.
